PRINTING Application filed July 23,

This invention relates to printing machines of that type whereinprinting devices for printing addresses or other matter are run from astack one at a time through printing position and it has for its primaryobject to provide means for distributing impressions from parts of theprinting device in separate column spacings on a sheet.

The present invention is particularly useful in preparing pay rolls, taxdata, subscription records, factory records and for a great many otherpurposes where a list is desired having certain data on separate linesor on separate columns as, for example, to have the name and the addresson the same line but in separate columns.

Another important object of the invention is to provide a machine whichwill carry the sheet to be printed bodily in two different directions todispose the paper with respect to the printing device so that parts ofthe printing form will be printed on the same line and in diflerentcolumns on the sheet.

platens and sheet carrying means correlated toprint parts of the form ofa printing device on the same line and in separate columns on the sheet.

And a further object is to provide a ma chine which is compact andsimple in construction, and Which operates automatically for causingcertain lines of a printing device form to be printed intermittently ona sheet, and in predetermined positions both horizontally andvertically.

The accompanying drawings illustrate a' machine embodying this inventionand the views therein'are as follows: I

of a type which may be used in connection with this invention.

Figs. 10, 10 and 10 are diagrammatic views of a sheet of paper showingthe various steps of the printing operation.

Referring to the drawings 1 designates a suitable frame which supports adrive shaft'2 driven in any suitable manner as by an electric motor,(not shown). A bevel gear 3 is mounted on the drive shaft and it mesheswith another bevel gear 4 fixed on a transverse shaft 5. ,An arm 6 isfixed on the shaft 5 and rotatable therewith. A casing 7 is mounted onthe top of the frame which supports a horizontal rod 8 which operatesthe platen mechanism. A short shaft 10 is secured in the end 9 of thecasing 7 and carries a loosely mounted member 11. A rod or arm 12 hasone end thereof connectedto one edge of the member 11, Figs. 2 and 5 andthe other end to one edge of the arm 6. Through this connection rotationof the drive shaft 2 causes oscillatory movement of the member A furtherobject of the invention is to pro- 11 vide a machine with intermittentlyoperated 10 and straddles the member 11 as shown in Fig. 3. A plate 14is loosely mounted on the shaft 10. This plate has an outwardlyprojecting stud 15 and a stud shaft 16 arranged thereon. An arm17 hasone end pivotal- A yoke 13 is loosely arranged on the shaft 1y mountedon the stud shaft 16 and the other end pivotally connected to a link 18'cated near its apex'and the stud'15, Fig. 3, is

located near its base. A bar 22 is arranged on this plate and is free topivot thereon. The bar carries a finger 23, Fig. 5, to which a spring-24 is attached to hold the bar upwardly. The finger 23 extends beyondthe face of theplate 14 and on the side opposite that to which the rod21 is fastened. A lug 25 fastened onrthe lower end of the member 11projects outwardly therefrom and is free pawl is held down or in normalposition to abut against the top 26 of the bar 22. The downward movementof the member 11 causes the lug 25 to engage the bar 22, and causes theplate 14 to follow that movement. A spring 27 attached to the arm 17,causes the plate 14 to return to its original or normal position. Theplate 19 has a bevel edge 28, Fig. 5, and when the lever 20 is down thefinger 23 is free to clear the plate. However, when the lever 20 is upthe beveled edge 28 of the plate 19 moves downward a sufficient distanceto cause the finger 23 to contact with the beveled edge of the plate 19and to ride thereon which pulls the bar 22 away from engagement with thelug on the member 11 so that the plate 14 andthe rod 8 will remain idle.The lever 20 is connected to the printing device feeding means whichcauses the lever to be raised upwardly when no devices are fed and thusprevents operation of the platen or rotation of the carrying shaft.Further explanation of the platen and carrying shaft will be made duringthe progress of this application.

A gear 30 fixed on the drive shaft 2 meshes with a gear 31 fixed on ashaft 32 which is mounted in the frame 1 and parallel with the drivingshaft 2, Fig. 2. A downwardly extending arm 33 is pivotally mounted onthe frame 1 and carries two rollers 34 and 35, Fig. 1. These rollers arepivotally mounted on short shafts 36 extending outwardly and rearwardlyfrom the arm 33 and are free to revolve thereon. A cam 37, Figs. 1 and2, ad-

jacent the arm 33, is fixed to the gear 31 and operates between therollers 34 and 35. Rotation of the cam causes alternate engagement witheach of the rollers and moves the arm 33 back and forth in the directionof the high spot of the cam. Rotation of the shaft 2 therefore rotatesthe large gear 31 and the cam 37, and causes reciprocation or rockingmovement of the arm 33.

A bar 39, Fig. 1, is pivotally mounted on the side of the frame at 38and carries a yoke 40 which is rigidly fastened thereto. This yokeengages a double flanged member 41 which is fixedly secured to thecarrying shaft 42. A link 43 pivotally connects the bar 39 with the arm33. Thus, reciprocation of the arm 33 causes reciprocation of the bar 39which in turn, through its connection with the yoke 40 and the doubleflanged member 41, moves the carrying shaft longitudinally. The carryingshaft 42 is supported in a sleeve 44 mounted in the frame and is free torotate therein.

A ratchet wheel 45, Figs. 2 and 3, is fixedly to rotate this wheel andthe shaft 42. This against the ratchet by means of a spring 49 which isalso attached to one of the side members of the frame. The yoke and theratchet are timed so that rocking movement of the yoke 13 causes thepawl 48 to ride on the ratchet a distance slightly greater than thewidth of one of the large teeth. Therefore, rocking movement of the yoke13 moves the pawl 48 on the ratchet and alternately engages a largetooth and a small tooth which rotates the carrying shaft a distanceequal to either one of these teeth. lVhen the ratchet moves the carryingshaft the distance of a small notch, it is equivalent to the distancebetween the last line and the next to the last line of a printing deviceof the type shown in Fig. 9. Rotation of the carrying shaft 42 thedistance of a large tooth is equivalent to the distance between thehorizontal parallel lines on the sheet shown in Figs. 10, 10, and 10.Rather than move the printing device, which would be an intricateoperation and which, no doubt, would require too fin'e an adjustment forperfect and speedy printing, it has been found preferable to move thesheet a sufficient distance to get the different lines of printing inproper lineal position on the sheet.

A reel comprising a plurality of wheels 50 fixedly attached to thecarrying shaft 42 is adapted to support-and carry a sheet which may beprinted in blank as shown in Figs. 10, 10", and 10. Suitable braces 51connect these wheels at intervals and keep the same in spaced relationto each other, and add strength and rigidity thereto. A rod 52 extendingthroughsuitable lugs 53 formed on the wheels, and free to move therein,is provided with a plurality of pins 54, Figs. 7 and 8. A finger 55 ispivotally mounted on the rim of each of these wheels and it has anupturned edge 56 which is adapted to be engaged by the pins 54 on therod 52. A spring 57 holds these fingers tightly against the outside edgeor rim of the reel. The reel may be recessed to form a seat 58 for thefingers 55, thereby providing an even and full bearing for the fingersto properly hold the paper in position. on the outer end of the rod 52is a lever 59, Fig. 1, whereby movement thereof causes the pins 54 toengage the fingers and raise them upwardly. The spring 57 actsoppositely thereto and in normal position holds these fingers in theseats 58 in the wheels 50. Rollers 61 are arranged on the spokes of thewheels to engage a rod 62 pivotally mounted on the carrying shaft.Longitudinal movement of the carrying shaft supports the reel on the rod62 and causes the reel to maintain its normal position at all times,throughout the entire operation of the machine.

Links 63 are fixed to the rod 8 and are curved to provide clearance fromthe sleeve 44. An intermediate support 66 has a yoke 67 pivotallyconnected thereto near the rearward edge thereof. -A platen casing 68has a pair of upwardly disposed arms 69 which are pivotally connected tothe yoke. Ears 7O struck up from the platen'casing 68 are pivotallyconnected to the curved links 63 by means of straight links 71. A pairof arms 72 have one end pivotally connected to the frame support 66 andthe other end pivoted to a rod 7 3 extending through the ears 70 of theplaten frame. Through this mechanism oscillation or rocking movement ofthe rod 8 causes vertical reciprocation of the platen casing. A pair ofplatens 75 and 76, Figs. 7 and 8 are arranged within the platen casingand are held upwardly by spring 74. Rods 77 extend through the platencasing and are cut away to form cam faces 77 which contact with the topof the platens so that oscillation of the rods will alternatereciprocation of the platens. A pair of levers78 are fastened to therods 77 and are pivotally connected together by a link 79. A projection80 integrally connected to the link '7 9 is adapted to be engaged byadisk 81 connected to one of the wheels 50. A spring 82 fastened to oneof these levers 78 normally holds the levers in a predetermined positionand causes one of the platen membersto be in printing position. Uponreturn movement of the carrying shaft, the wheel having the disk 81 willstrike the projection 80 and 0s cillate the rods 77 in the directionopposite to that shown in Fig. 4. This movement oscillates the rodsninety degrees and causes the platen which was in normal printingposition, to be raised and causes the other platen to be lowered intoprinting position. As the carrying shaft moves to the left, Fig. 4, theprojection 80 is released and the spring 82 pulls the levers back tonormal position; this operation alternates .th printing pos1 tion of theplatens.

A magazine 83 is mounted on the frame, Fig. 2, and is adapted to carry astack of printing devices which may be of the kind shown in Fig. 9.These devices are fed from V the bottom ofthe stack by means of a chain84 carried by suitable sprockets 85. The chain has suitable projections86 fastened thereto at intervals which take a printing device from thebottom of the stack and carry it along to printing position underneaththe platen. The chain and the carry ing mechanism is operated in anysuitable manner as is well known in the art and no further descriptionthereofis required in f this application.

A pair of longitudinal members 87 and 88 having bevelled outer ends 89and 90 are arranged in the casing 7, Fig.4, and held in normal positionbyzset screws 91; the rod- 8 extends through the lower longitudinalmember 88 and is free to move vertically therein.

position, with aportion of the These members permit vertical adjustmentof the rod 8 to accommodate reels of different sizes for sheets ofdifferent sizes. Adjustment is obtained by loosening the set screws 91and adjusting the set screw 92 to move the member 87 relative to themember 88' after nally and circumferentially to carry the sheet intoprinting position to receive an impression and another part or all therest of the printing form on the sheet in another column but on the sameline with the first impression, as shown in Fig. 10. When impressionshave been made from all ing devices to be printed the reel moveslongitudinally and circumferentially, and returns to initial position,which is first impression sheet in printing position to receive a partof the next printing device in the first column to be printed and on thenext line. At the same time a new printing device is fed into printingposition and this completes one cycle of operation of the machine.

In Fig. 9 I have shown a printing device having a form which compriseson one line the name of a person, on the next line his occupation, andon the third line certain personal information with respect to theperson.

A sheet is printed in blank to receive the in- 10". This is a simpleexample of the use of my invention and it is selected for convenience indescriblng the inventlon and not to limit the lnvention to printing aparticular number parts of the print of lines in any particular numberof columns.
